IMPROVEMENT lN SUGAR-EVAPORATORS.

Specification forming part of Letters Patent No. 40,934, dated December15, 186-.

To all whom it may concern.-

Be it known that I JAMES HIGH, of \Val nut Fork, in the county of Jonesand State of Iowa, have invented a-newand Improved Evaporator forsaccharine Liquids, 850.; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 represents a longitudinal vertical section of myinvention. Fig.2 is a transverse vertical section of the same. Fig. 3 isa plan or top view of the same.

Similar letters of referencein the three views indicate correspondingparts.

This invent-ion relates to evaporators pro vided with a transverse trackat the rear end of the flue, in combination with two wheeled pans andwith a stationary heatinpan in such a manner that the juice after it hasbeen boiled in the heating-pan and freed fromscum can be convenientlyladled over into either of the wheeled pans and exposed to a moderateheat over the rear end of theiiue, for the purpose of finishing thesirup, and that one of said wheeled pans 'can be emptied while thecontents of the other are finished.

The invention particularly consists in the use of wheels mounted on thesides in such a eight (more or less) compartments by means of transversepartitions a, with openings at opposite ends, so that the. juice iscompelled to pass through the pan in a zigzag channel,

and that in its passage from one side of the pan to the other, wheneverit reaches the middle or hottest portion of the bottom, the scum risesand is thrown toward the sides,\vlre1-e it can be readily removed. Inthis manner the juice is perfectly freed from all scum and otherimpurities, and the clear juice collects in the last or eighthcompartment. From this compartment it is ladled over' into one of thepans D D, which is provided with wheels 1), running on a track, E. Thistrack is secured ontherear end of the furnace A, and it we tends in alateraldireetion over both sides of the same far enough to permit ofmoving either of the pans D D over the rearv end of the flue B. A curvedshield, 0, which rises from the rear end of the pan 0, and extends overthe edge of the pans D D, prevents the loss of juice during the ladlingoperation.

The pans l) D may either be made so that they form two eompartin'rentsof one and the same pan, or they might be made separate and placed sideby side. During the time one of these pans is over the fine in order tofinish its contents, the finish ed sirup can'be convenient] y drawn fromthe other pan, and vice versa, so that no time is lost.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination, with the finishing-pans D D, mounted on wheels attachedto their sides, as herein shown and described, of the guard 0, supportedon either the stationary or moving pans and projecting over the spacebetween the two,'iu the manner and for the purposes specified. JAMESHIGH.
